PROBLEM TO BE SOLVED: To obtain a control device with which the output of an engine and the output of a second motor are transmitted with good efficiency to the side of a drive wheel by a method, wherein the sun gear of a planetary gear and a carrier are fastened by a lockup clutch, and a first motor which is connected between the output shaft of the engine and the sun gear of the planetary gear control is made simple in a parallel running operation, in which the driving force of the second motor on the side of a ring gear is added to the drive force of the engine on the side of the sun gear so as to be output from the carrier. SOLUTION: When a series running mode is shifted to a parallel running mode, a torque-0 command is given to a motor-A controller which controls the speed of rotation of a motor A, and the motor A is set (S301) at a torque 0. A vehicle drive torque Tall, which is calculated on the basis of an accelerator-pedal pressed amount is distributed to an engine and a motor B, by taking into consideration the remaining capacity of a battery, a torque command is given to the engine, and a torque command is given (S302 to S309) to the motor B. As a result, in the parallel running mode, the drive force of the engine and that of the motor are transmitted with good efficiency to the side of the drive wheel, without being impeded by the motor A. |
